No longer a question of if, it's really a matter of when the US—like Canada—will legalize recreational marijuana use. As producers in states that have already embraced the bud can attest to, a commercial endeavor in the weed industry leads to competition, marketing and more. To prevent that from getting out of hand (in Canada) medical researcher Francois Gagnon has proposed a unique idea: "delete the demand-driven profitability part of the equation by establishing a non-profit model for distribution" led by a universal agency, according to Fast Company. This solves everything from insuring standards to controlling overt advertising. You can read more of Gagnon's plan at Fast Company.
